Matthew de Mount Martin is not mentioned in the VCH parish history and if he held the main manor of Westbourne how he came to hold it is unclear. In 1302 the manor was held Richard FitzAlan, Earl of Arundel. A location near to the church, at the given map reference, is likely for the main manor house. However it is possible the Mount Martin house was a sub-manor somewhere else with the local area. The lack of even slight earthworks suggests the manor house was mainly timber and is unlikely to have been a strongly defended house.

Minor archaeological investigations, such as watching brief reports, and some other 'grey' literature is most likely to be held by H.E.R.s but is often poorly referenced and is unlikely to be recorded here, or elsewhere, but some suggestions can be found here.

The possible site or monument is represented on maps as a point location. This is a guide only. It should be noted that OS grid references defines an area, not a point location. In practice this means the actual center of the site or monument may often, but not always, be to the North East of the point shown. Locations derived from OS grid references and from latitude longitiude may differ by a small distance.
Further information on mapping and location can be seen at this link.
